Setting autoCommit to false not working with Primavera SDK

 Hi,
I'm using the following JAVA code to insert some resources:

------------------------------------------------------------------------------------------------------------------------------
            .......
            Connection con = null;
            Statement stmt = null;
            Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
            con = DriverManager.getConnection("jdbc:odbc:P6SDKODBC","admin","admin");
            con.setAutoCommit(false);
            stmt = con.createStatement();
            stmt.executeUpdate("INSERT INTO RSRC (rsrc_id) VALUES (0)");
            .......
            con.commit();
------------------------------------------------------------------------------------------------------------------------------


However, the record is inserted into the database even before the con.commit() is called.

Thanks for your help,
Praveen.
